Gene name	Name=ulaG;

Comments [?]

FUNCTION	Probably catalyzes the hydrolysis of L-ascorbate-6-P into 3- keto-L-gulonate-6-P. Is essential for L-ascorbate utilization under anaerobic conditions.
CATALYTIC ACTIVITY	Reaction=L-ascorbate 6-phosphate + H2O = 3-dehydro-L-gulonate 6- phosphate; Xref=Rhea:RHEA:28803, ChEBI:CHEBI:15377, ChEBI:CHEBI:58774, ChEBI:CHEBI:61698;
COFACTOR	Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
PATHWAY	Cofactor degradation; L-ascorbate degradation; D-xylulose 5- phosphate from L-ascorbate: step 1/4.
SUBCELLULAR LOCATION	Cytoplasm.
INDUCTION	Induced by L-ascorbate. Repressed by UlaR.
SIMILARITY	Belongs to the UlaG family.
